WASHINGTON: Getting an injection could soon be a painless experience, as MIT scientist have devised a new device which they say shoots drugs through the skin at nearly the speed of sound without using needles. The high-speed jet injector device, developed by a team at the Massachusetts Institute of Technology, uses a small, powerful magnet and electric current to inject medicine at nearly the speed of sound.
Changes in the electric current allow the injector to work in two phases - a highspeed phase to enter the skin and reach a certain depth, and a lower-pressure phase to deliver the drug in a slow stream that allows for absorption , said Catherine Hogan , a member of the team. "If you are afraid of needles and have to frequently selfinject , compliance can be an issue," Hogan was quoted as saying by LiveScience. "We think this kind of technology ... gets around some of the phobias that people may have about needles," he added.
The jet injector delivers its drugs through an opening as wide as a mosquito's proboscis. Several "jet injectors" already exist, but they lack the ability to control drug injection speeds like MIT's device.
